Unvented service (G3) 

An un-vented cylinder is governed by G3 of the building regulations. It has many safety controls which should be checked on an annual basis or and on a change of a tenancy.

It is also used to satisfy most insurance companies and manufacturers to honour a warranty claim. You may be asked to produce proof of regular maintenance should an incident occur.
